Figure 6. Muscle module – reconstructed activation pattern of subjects with no impairment: (A) Subject 15, (B) Subject 16.

Note that a subset of the muscle modules (c _j) and their tuning curves (W _ij) were similar between these two subjects (i.e., module 2 of both subjects, module 1 of subject 15 and module 3 of subject 16, and module 4 of subject 15 and module 1 of subject 16).
